STREET-INDICATING nnvzcn! To. all whom it may concern:

a t Be it known that I, THOMAS W. SMALL, a

cator in place. Fig.0 is a'p'e'rspectivelview citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented a, certain-new and useful Improvement inStreet-Indicating Devices, of which the following is a full, clear,and-exact description, reference being had to the accompanying drawings.

This invention relates to street or station indicators adapted to becarried by arailway car orother vehicle, and operated manually orautomatically to disclose desired indications. 4

One of the objects ofthe invention is to provide such indicatingdevicewith an indicator facing in two directions so that with the devicelocated in an intermediate portionof the car, the indication maybe seenfrom either'directlon.

Another object is to arrange the indicator so that its indication may beseen from below.

it, enabling the indicator to be. efficiently carried by the roof of thecar.

Another'ob 'ec-t is to-{provide simple and efficient means fOII'inclosing the indicator and allowing access to the'interior.

Another object is to provide mechanism. preventing -inopportune orfaulty operation of the indicator; I

l attain the above results by mechanism illustrated-herein andhereinafte'r more fully described.-

,T he drawings show my indicator embodied in an approved form.

Figure 1 is a perspective view of the indicator in its case, a portionofthe case at one corner being broken away to disclose'the interior. Fig.2 isv afront elevation of the indicator with the front portion of thecasing removed. Fig. 3 is a cross section through spring barrelswh'icl-i carries the, end of the indicating band or taper Figs.'6 and 7are vertical cross sections of the indicator substantlally on the lines6-6 and 7 '7 respec tivcly of Fig. 2,'lookingto the left.

of the magnetic operating mechanism and its safety appliancesflw i v'" iAs shown in the drawing, vertical frame plates 10, 11 and -12 rigidlyspaced by dis tance'bolts l5 are carried; by an outer'franie consistingof the supporting bars M eXtend 6O ing across the top, the supportingbar 15- e x tending across the bottom;saidfltiarshaving theirendsrespectivelyturned downwardlyand upwardly, and. the end plates 16-and '17 connected with such ends. 1 Mounted in the frame members 10 and11" are the spring barrels 2O and'21', each of which is adapted to carryone endof the band or tapewhich carries the indication, These springbarrels are'mounted on rods 22 journaled in the frame member'sfim'entioned, each barrel being hollow, and cal spring 23 occupying the boreanthbeiiig connected at one end with the barrel-vandal; the other endwith the rod-22. "Tl1e rods22 are coupled together by means of gears2401i the'two rods respectively'whiclr meshwith an intermediate gear 25.loosely carried on a: the frame plate 11. l w;

The tape or indicating band 30 is secured eo at one end to the springbarrel 20 ,ai1d,-as-- shown, passes off of-its under side beneath theguide roller 31- around the upper mate: as outer side of the drivingroller 32, thence :5 downwardly substantially parallel With one r sideof the indicator beneath theguide roller 22 33, thence upwardly aroundthe :out-erand 1 upper sideof the'other driving roller thence across theupper side of the guide roller 35 and downwardly substantially parallelwith the other side ofthe indicator beneath the guide roller 36 andthence u pwardl y; onto the springbarrel 21.. From this course" (2:; ofthe band it will be apparent that two portions'thereof may be exposed'tou'yiei'w at opposite sides of the indicator, namely, our? the oneside, theportion between the driving roller 32 and the:guide.roller,3'3.,- andonrtlie otherside, the portion betweenlthe guidrollers 35 and 36,1. Suitable windows. provided through which suchportionsi band are visible, the band beingdfrigven the rotation of thedrivingrollers-32 and, 3- The windows 47- and 48' are carriedbytl twoside members 40. and v l1 of the casm these side members being hinged,atthe r uppcredges to the top member 42.0f .thelras ing which is secured,to'the frame bars I At their lower edges videdwith hasps-"43 which areadapte to the casing sides are: ro-

ext'end;.0ver an ear 44 depending from the botto'm member 45 of thecasing. A suit able pin or lock 46 maybe applied through this earto holdthe casing si es in position'.

Aninspection of Fig.-3 will show that the side of the ribbon which isvisible through the window 47 is the outside face of the ribboh as itWinds onto either spring barrel, While the side which shows throughwindow 48 is i the inside face of the ribbon as it winds onto thebarrels."

The corresponding indications on the ribbon are printed such distancesapart that when one is showing through the window 47, the other will bevisible through the window 48. i

Fig. 8 is a conventional illustration of an electric car, wherein 50 maybe taken as representing the car itself, and 51 my indicator 1 completecarried by the roof of the car, sub-- stantially at mid position. Itwill be seen that the op osite faces 40 and 41 of the indi Eoator may eseen not only from the respective ends of the car but that one face orthe .pther may be seen from any intermediate point; in fact, one face orthe other is visible to a passenger standing directly beneath theindicator, t

. barrelbeing corres ondin ly rotated to take up the other end 0 the ribon. Inasmuch,

- however, asone barrel is decreasing in size as clock Work whichrotates t the intermediate the other is increasing,

-rovided to enable differential springs are rotation. T 's' feature iscovered in my Patent No. 738,366 granted September 8, 1903.

To drive the ribbon, I rovide suitable e driving roller 34, this rollerbeing geared with the roller 32 ratchet with the main 60 thespring. Themain which in turn is geared with the roller 31. I will'now desori ethis clock work. The

shaft 64 of the roller 34 extends through the frame plates 11 and 12 andcarries a sleeve 62.which is splined to the shaft so that it .rotatestherewith. Mounted between the frame members 11 and 12 is the driving sring-53,'one end of which is anchored and the other end secured to a pinconnected by a car 54. This pin may e key as 55 to wind up gear 54meshes with a pinion. 56 rigid with a gear 57 which meshes with pinions58 and 59, the latter pinion meshing with a pinion 61. Now either pini0n'58or 61 is adapted to mesh with the pinbe rotated by a suitab ion onthesleeve 62 according as that' sleeve is shifted inwardly or outwardly,whereby the force of the spring may drive the shaft 64 in one directionor the other, as

desired, itbeing only'necessary to shove inwardly or outwardly the head62 of the sleeve.

its end a gear7 2 which meshes with a pinion 73 on which is a'fiier 74.Pivctally carried by the frame 12 is a lever 75 which is connected atone end with the lever "71 and has its other end in position tojustjnorn ially clear the flier 74..

From the above described construction, it

follows that when the forward end of lever,

71 is pulled downward the train of: gearing is released at 70, but thelever 75 is brought into the path of the flier so movement'of thegearing takes' place. Then when the lever 71 is returned to normalposition, the rotation continues until the head 69 has made a completerotation, the pin 70 again coming into engagement with the lever.Therefore, to cause an effective release of of the ribbon, it isnecessary to not only ull down the forward end of the lever 7'1 ut alsoto release such lever. It is therefore impossible for the mechanism torun contin uously by reason of the lever being inadvertently held down.The ribbon is fed forward for each actuation of the lever only theproper distance to indicate the next station, and any-subsequent advanceof the ribbon requires subsequent actuation of the lever.

This is of particularimportance "where the lever 71 is operatedmagnetically by the automatic closure of a circuit due to the cararriving at certain points, for if the car should stopat these pointsthe magnet might hold down the lever for a considerable time. With mymechanism no actuation would be given the band until the car had resumedits travel and cleared that circuit closure.

The lever 71 may be actuated by any suitable means. For-this purpose Ihave shown an electro-magnet 77 mounted on -'a block 78 carried by theframe member 12 and having an armature 7 9 connected with the lever 71.An energization and subsequent release of this ,Inagnet, manually orautomatically, may therefore release the clock work to ad Vance theribbon one step.

To prevent the lever 71 inadvertently jarring away from the projection70 in the running of the car, I provide the gate 80 which is secured toa rock sha t 81 loosely j ournaled that only a slight the gearing toeffect an advancement above the lever 71 ainj lrovidd with acounterweight -82. This rra'ngement of parts is best shown-in Fig. 9, ithaving been omittedfrom Fig.3 so as not to encumber that figure I withtoo many lines and thus obscure more- 'im ortant parts. Thiscounterweight nor- :ma ly holds the gate with its lower edge just aslight distance above-the lever, preventing it from materially rising.Above the magnet is a bell cran'83k, one arm of which is con- ,nected bya link 84 with the gate 80 and the 1 its forward end. There is a smallamount of playfbetween the gate and'the lever 71, and -.as the magnetpulls the armature downward, the first portion of the movement, Whilesuch loosen'e ss is being. taken up, operates .to swing the gate 80 awayfrom the lever so that other arm by a link 85 with the lever 71 near Ithe rear-end of the lever may rise, the gate swinging u ward faster thanthe lever below it rises. he play between the gate and the lever is sosmall that the lever cannot normally rise high enough to release theprojection.
